The answer is AB = 6.

External value x (external value + internal value) =
External value x (external value + internal value) of the other side

Substitute, transpose, and simplify.

TA x (TA + AB) = TC x (TC + CD)
10 x (10 + (x + 2)) = 8 x (8 + 12)
120 + 10x = 160
10x = 40
x = 4

To find AB: x + 12; x = 4
AB = x + 2
AB = 4 + 2
AB = 6

Y=143.3(5)^2+1823.3(5)+6820

MA_775_DIABLO [31]

As the question is written, the <em>correct answer</em> is:

19519.

Explanation:

Our question states

y = 143.3(5)² + 1823.3(5) + 6820

To evaluate this, we use the order of operations (PEMDAS). There is nothing to be evaluated in parentheses, so P is taken care of.

The E part, exponents, is 5². This is 25, which gives us:

y = 143.3(25) + 1823.3(5) + 6820

Next we have M and D, multiplication and division (in the order they appear). Our multiplication is:

143.3(25) = 3582.5; and

1823.3(5) = 9116.5.

This gives us:

y = 3582.5 + 9116.5 + 6820

Lastly, we add these:

y = 12699 + 6820

y = 19519
